Weed of the Week #1122 Foxtail Barley (Air Date 10-6-19)


D: Our Weed of the Week
is foxtail barley. B: Foxtail barley is just a
short lived perennial weed – doesn’t have rhizomes or
anything like that, but boy, this has been a tough weed
here for the last few years, kind of spreading across the
United States. We’re going to talk today about how to
solve this problem on your farm. D: You know some of
the toughest areas, Brian, have been reduced-till,
no-till, pastures, roadside ditches, these kinds of
places where we’re not doing any tillage. If we just did
some tillage, Brian, we’d probably stop our Weed of
the Week. B: Hey, don’t forget about sodic and
saline soils – this weed is a little bit tolerant to
those soils as well. Now let me start in pastures. Ok, a
lot of times what we talk about is – let’s forget
about herbicides entirely for a second. The biggest
thing – and just like Darren mentioned – in some of these
tough areas well, what is it? It’s lack of crop
canopy. So if you have this problem in your pasture,
that tells me, “Hey maybe there isn’t the right
fertility program out there. Maybe we need to move to
rotational grazing and not overgraze that pasture.” If
you let that pasture compete, well it has a
pretty good chance against the foxtail barley, but once
it gets behind the 8-ball in the spring, well then you’re
going to have a problem. D: Well the same thing in our
crop fields, too, if we’re raising a good healthy crop
and we’re keeping the soil in balance, like you
mentioned – we get into a salty or sodic area – we’re
going to have trouble growing crop out there and
that’s a problem. B: Ok, so in terms of herbicides to
control foxtail barley – Roundup is excellent on it,
but just understand it’s going to take more Roundup
than it would to kill foxtail for example – just
regular foxtail – green or yellow. You’re going to need
the full labeled rate and then you’ll do pretty well
on this particular weed. Now out in pastures it gets
tough, because, yes we’ve got Plateau and Pastora – I
mean there are a few grass killers in pastures for
certain grasses, but boy, they’re not going to do a
whole lot on this perennial foxtail barley. So
unfortunately, if you had a pasture and you had a major
problem, I’d suggest using Roundup – wipe out the
pasture and start over. B: If you have this weed in
soybeans, start with a good pre – use one of the
yellows especially – Trifluralin, Sonalan, or
Prowl. Follow post-emerge with one of the grass
killers – Select Max or something with clethodim in
it’s probably the best. In corn, I’d probably start
with one of the group 15s, then follow post-emerge with
Accent, unless you have the ability to use Roundup or
Liberty in your crop. And then finally, in wheat,
start with something like Pre-Pare, follow post-emerge
with Axial, or maybe it’s Everest. I mean, you’ve got
some options, but just understand – there’s nothing
that is fantastic on this weed in wheat. D: That’s all
the time we have for this week’s weed, but Iron Talk
is coming up next.
